Scenario-Based Analysis of the Adequacy of a South African Grid to Supply Peak Demand in 2030
The transmission development plan (TDP) is updated annually in South Africa. The TDP identifies projects to strengthen the network to supply future load demand and integrate new power generation plants. The TDP of the grid investigated is planned with all the generation units in each of the power stations supplying the grid in service. However, outages can occur on the power station units, resulting in the grid being inadequate to supply the peak network load demand during this period. The paper demonstrates the scenarioplanning approach in investigating the adequacy of a power transmission grid with multiple generation injection points to meet peak load demand under multiple generation scenarios. The investigation is performed on the 2030 network of a power transmission grid in South Africa. It is found that even though the TDP of the power transmission grid is planned with all the generation units of the power stations supplying the grid in service, there is adequate network capacity in the year 2030 to supply the peak load demand when multiple generation scenarios are investigated. Also, the benefits of analysing multiple generation scenarios to ensure that the power transmission grid has enough capacity to supply the peak load demand in a given time interval of study are highlighted.
